Projectile Motion
Example 2

What does the equation h(t) = -16t2 + 32t + 48 say about the projectile?

Step 1. Determine the initial height of the object and its initial velocity.

The initial height, s, is 48 feet. The initial velocity, v, is 32 ft/sec.

Step 2. State what these values represent.

The -16 shows that gravity pulls the object downward. The object is being thrown or projected at a velocity of 32 ft/sec. The object is thrown from a height of 48 ft.
